What it does
Canvas Render is an agent skill from LiberatedPixelCup/Universal-LPC-Spritesheet-Character-Generator. Change the offscreen renderer, palette recolor, z-position order, or magenta mask, and ask the user to check WebGL and the CPU fallback. Use when editing sources/canvas/, palette recolor, z-positions, or renderer output.
Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering 3D graphics and WebGL. The repository describes itself as: Character Generator based on Universal-LPC-Spritesheet. The licence is GPL-3.0.
When your agent uses it
- Editing sources/canvas/
- Palette recolor
- Renderer output
Example prompts
- “/canvas-render”
What it can do on your machine
Read from SKILL.md and the folder at commit 58ce1aa. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Canvas Render loads about 314 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 89 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Canvas render
Palette recoloring is the only WebGL/CPU branch, in recolorImage() in
sources/canvas/palette-recolor.ts.
The two implementations can disagree, and only one runs on a given machine.
You cannot confirm both paths. Ask the user to follow
Force CPU Mode and
Visual Verification:
setPaletteRecolorMode("cpu"), then setPaletteRecolorMode("webgl"), and
compare with getPaletteRecolorStats().
Lower zPos draws first and ends up behind
(ARCHITECTURE.md). Magenta #FF2CE6 is
keyed out in sources/canvas/mask.ts.
ZIP export drawing and render timing (WebGL and CPU) are a separate check: performance-profiling. Visual correctness of both recolor paths is still this skill.
